Evolution Collated Tough Board Screw 3.9x19mm - box of 1000

Application

Fixing dense and hard surfaced boards to both drywall track and timber base materials. IMPORTANT APPLICATION ADVICE: On rare occasions black phosphate screw coatings can react with some render types, which can damage the coating resulting in corrosion and staining. To reduce the risk of this happening Evolution recommends sealing the drywall screw heads with a PVA bonding solution before render is applied.
